Description
50T steelmaking electric arc furnace: The electric arc furnace body is in the shape of a teapot, which is a steelmaking reaction vessel.
The furnace body consists of a furnace body and a furnace cover (furnace top).
The outer shell of the furnace body is made of steel plate, and the inside is the furnace lining.
The furnace wall is built with magnesia brick (MgO) or chrome magnesia brick (Cr2O3, MgO).
The bottom of the furnace is in the shape of a basin, and there is a layer of magnesia burning (playing) on the clay bricks and magnesia bricks.
The acid furnace lining is built with quartz brick (SiO2) and quartz sand.
In addition to the basic requirements of strength, high temperature resistance and heat insulation, the furnace lining refractory material is also required to withstand chemical erosion of slag, thermal shock of repeated rapid changes in furnace temperature, and collision between furnace blocks and operating machinery.
Features:
Use:
This steelmaking electric arc furnace adopts alkaline lining, and can melt carbon steel, high-quality carbon steel, alloy steel, stainless steel and other varieties.
Structural Features:
50t steelmaking electric arc furnace, the structure adopts the furnace cover to remove the top charging, (EBT) or tapping nozzle, and the right or left operation is selected by the user.
Electrode lifting, furnace body tilting, furnace cover lifting and rotation are all hydraulic.
The control adopts PLC intelligent regulator control.
